Patented May 19', 1931 WILLIAM H. TRIMIBLE AND JOHN CLARK, 01? DALLAS, TEXAS BATTER-Y TERMINAL CLAMP Application filed February 4, 1929. Serial No. 337,351.

This invention relates to means for clam-ping one object to another, the invention being mainly designed for clamping a conductor terminal to a battery post, the general object of the invention being to provide means whereby the terminal can be easily and quickly clamped to the post without the use of screws, bolts or the like.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawingswherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a partial plan view of a battery, s'howin the preferred form of clamp used to attagi the terminal to the post of the batter v j Figure 2 is a section on line 2.2 of Fig 25 ure 1.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a perspective view of the body formed with a recess 10 which has one end of the terminal.

33 Figure 5 is a perspective view of the eccentric ring.

Figure 6 1s a sectionalview through the body, showing a modification.

Figure 7 is a plan view of said 'modifica- Figure 8 is a plan view cation.

Figure 9 is a side view partly is section, of said modification. Figure 10 is a sectionalview showinganother modification. Referring to Figures 1 to 5, the numeral 1 indicates the body of the terminal which is formed with a socket 2 to receive the end of the cable or conductor 3 and said body is formed with the ring-shaped parts 4 which extend from one side of the body adjacent an E end thereof, these ring-shaped parts being s aced apart and they are adapted to fit over the post 5 of the battery B or other object of another modifi to which the body is to be connected. -A ring 6, having its opening 7 eccentrically arranged, fits between the ring parts 4 and the opening 7 receives the post. This ring 7 is provided with the handle 8 and as will be seen, when the ring is turned through means of its handle, the engagement of a part of the outer circumference of the ring with the wall between the two ring parts 4 will cause the walls of the opening 7 to frictionally engage the post and thus set up a clamping action which will lock the device to the post. A slight blow on the handle will cause the ring 6 and the ring parts 4 to so engage the post that the device will be firmly locked to the post and there will be no danger of the parts becoming detached. A blow in the opposite direction will act to loosen the clampfrom the ost.

T us it will be seen that we have provided simple means for attaching a terminal to a battery 0st without the use of screws, bolts post.

In themodification shown in Figures 6 and 7, the. body-1 is formed with an opening 9 to receive the post 5 and said body is also communicating with the opening 9. A member 11 is placed in the central part of the re-.' cess andis formed with oppositely arranged semi-circular recesses 12, one of which receives a portion of the post and the other of which receives a portion of an eccentric member 13 which is fastened in the recess by a in 14. The eccentric is provided with a andle15 whereby it can be partly rotated to cause the member 11 to frictionally engage the post so as to clamp the terminal to the post. By movingthe eccentric in an' oppo- Tsite direction, the clamping action ofkthe member 11 will be released so that the terminal can be removed from the post.

In the modification shown in Figures 8 and 9, one end of the body 1" is formed with a substantially semi-circular recess'9'- to receivei' -portion of the post 5" and this body is also formed with a recess in its upper portion in' whichfis placed the eccentric 13 and a or the li e and the terminal can be easily and body having a pair of ringshaped parts band 16, preferably of metal, passes around the post and the eccentric so that movement of the eccentric will cause the band to grip the post and thus lock the terminal to the a post. This eccentric is also provided with a handle 15.

In the modification shown in Figure 10, the body 1 is formed with an opening 9 to receive the post and it is also formed with a recess 10' to receive a member 11' having a-semi-circular recess-to receive'part of the post. The body is also provided with ahole which communicates with the recess and into which a wedge 17 is adapted to be driven so that said wedge will force the inember 11" against the post and thus cause said member tolock the terminal to the post.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily a parent.

It is to be understodd that c angesmay be made in the construction and in the combination and arrangement of 'the several parts, provided that such changes fall within the scope of the appended claims.

What we claim is p c 1. A battery terminal clamp comprising a spaced a art with their openings in alignment an a curved wall connecting portions of the ring shaped parts together, a ring rotatably arranged between the ring parts and having a part contactingttheinner face of the curved wall, said ring having an eccentric opening therein to receive the battery post and a'handle connects 'l with the ring and having an upwardly extending part.

2. A battery terminal clamp comprising a body provided with a. cable receiving means and having a pair of ringsshapedparts connected together in spaced relation and having their openings in alignment, a ring rotatably arranged between the ring parts, a handle connected to the ring and having an upwardly extending part and means whereby movement of the ring will displace its opening in relation to the openings-in the ring parts so that the ring parts and the ring will gri a battery post;

11 testimony whereof we aifix our sigma-- tures.
